Background The objective was to study ovarian reserve values in women of early reproductive age with polycystic ovary syndrome (PCOS) according to their phenotype. Materials and methods Two hundred women of early reproductive age with PCOS and without PCOS were studied by clinical, laboratory (hormonal), ultrasound and statistical methods. Results The anti-Müllerian hormone (AMH) index in women with PCOS with the main (A) and non-androgenic (D) phenotypes corresponded to a high level, with anovulatory (B), ovulatory (C) corresponding to a normal level. AMH in women with the main (A) phenotype differed and was higher compared with women with anovulatory (B) and ovulatory (C) phenotypes and had no differences to women with the non-androgenic (D) phenotype. No differences in the AMH level between anovulatory (B) and ovulatory (C) phenotypes have been established. Ultrasound parameters of the ovaries (volume, number of antral follicles in the section, average diameter of the follicles) of women with PCOS of the main (A), ovulatory (C) and non-androgenic (D) phenotypes were statistically significantly larger than healthy ones. With anovulatory (B) phenotype these figures did not differ from the control group. When comparing phenotypes by ultrasound parameters of the ovaries the main (A), ovulatory (C) and non-androgenic (D) phenotypes did not have any differences among themselves. Anovulatory phenotype (B) had lower ultrasound indices. Conclusion The study of indicators of ovarian reserve in women of early reproductive age with PCOS is a promising direction that will allow to more accurately determine the reproductive potential of each particular woman and influence the choice of treatment tactics.
